DTMF Dialing Mode.
This bit should be set during DTMF dialing in CTR21 mode if LCS[3:0] < 6.
0 = Normal operation.
1 = Increase headroom for DTMF dialing.
Force Japan DC Termination Mode.
0 = Normal Gain
1 = When register 16, DCT[1:0], is set to 10b (FCC Mode), setting this bit will force
Japan dc termination mode while allowing for a transmit level of –1 dBm. See
“DTMF Dialing” on page 26.
Line Voltage Adjust.
When set, this bit will adjust the TIP-RING line voltage. Lowering this voltage will
improve margin in low voltage countries. Raising this voltage may improve distortion
performance.
00 = Normal.
01 = –0.125 V.
10 = 0.25 V.
11 = 0.125 V.
Current Limit.
00 = All other modes.
11 = CTR21 mode.
Read returns zero.
